IMPROVEMENT IN RESERVOIR COOKING-STOVES.

Specification forming part of Letters Patent No. 146,969, dated January27, 1874; application filed January 16, 1874.

To all whom fit ma y concern:

Be it known that I, GURDON G. XVOLFE., of Troy, in the county ofRensselaer and in the State of N ew York, have invented certain new anduseful Improvements in Cooking-Stoves; and do hereby declare that thefollowing is afull, clear, and exact description thereof, referencebeing had to the accompanying drawing making a part of thisspeciiication, in whichy Figure 1 is a perspective view of the rear endof a stove containing my improved waterreservoir. Fig. 2 is a rearelevation of the same withthe reservoir and its casing removed. Fig. 3is a vertical section of said stove upon a line extending from front torear, through the center or ascending` flue, and Fig. 4 is a like viewof the same upon a line passing through one of the side or descendingues.

Letters of like name and kind refer to like parts in each of thefigures.

The design of my invention is to enable water within a reservoirattached to a stove to be heated in an expeditious manner withoutinterference in any material degree with the operation of the oven; andit consists in a cooking-stove provided .with a chamber for receivingand inclosing a water-reservoir situated in rear of the vertical iiuesand below the top plate, communicating at its lower side with thedescending lues by means of a dampered aperture, and having its frontcentral portion extended forward to the back ovenplate, substantially asand for the purpose herein after specified.

In the annexed drawing, A represents the top plate, B and B, the sideplates, and C the rear end plate, of a cooking-stove, provided with anoven, D, top ue E, and descending and ascending flues F and G,respectively, all in the usualma-nner. Secured to or upon the rear endof the stove, from the top plate A downward, is a casing, H, which has,preferably, such lateral dimensions as to bring its ends ilush with theside plates B B, while from front to rear, and in a vertical direction,the dimensions of said casing are suited to the capacity of thereservoir to be contained therein. From a point near the top plate Adownward to the lower side of the chamber I, formed by the casin g H,the end plate C is removed in rea-r of the center or ascending ilue G,so as to combine said ue and chamber, and cause the ascending current ofheated gases from the former to expand into and circulate through thelatter before escaping into and through the exit-iiue K. Near the lowerside of the chamber I the end plate C is removed in rear of eachdescending flue F, so as to form an opening, L, which corresponds insize to the transverse area of said iiue, so as to permit the contentsof the latter to pass rearward through the former into said chamber. Adamper, M, is provided for each opening L, which damper may be pivotedat its lower edge so as to turn forward and close the flue F whileunclosing said opening, as shown in the drawings, or it may beconstructed in any well-known manner, so as to enable said opening to beopened or closed without reference to said iiue. rEhe chamber I is nowready for the reception of the reservoir N, which, as seen, is supportedby the top plate h of the easing H, or in such a manner as to bring itsupper edge against the same, and has between its sides and bottom aspace for the circulation of the heated escaping products oi'combustion.

If desired, the upper end of the center or ascending flue G maycommunicate with the top oven-due E, in the usual manner, by means of adampered opening; but I prefer to have such' communication eut olf by afixed fluev strip, or by extending the rear oven-plate d upward at suchpoint to the top plate A.

The stove is now complete, and operates as follows: When the oven is notrequired for use, the dampers M and M are opened, and the heated gasesfrom the fuel-chamber pass rearward through the top oven-flue E,downward into the descending lues F and F, and rearward through saidopenings into the chamber I, from whence, after circulating around thereservoir N, said gases pass into the ascending iue G, and from thenceinto the exit-fine K, having, during their passage through said chamber,imparted a large percentage of their heat to the liquid contents of saidreservoir. When the oven is in use, the dampers M and M are closed, andthe heated gases pass downward through the entire length ofthedescending dues F and F into and through the usual bottom oven-flues,and thence upward through theascending flue G to the chamber l, intowhich they expand, and after circul ation around the reservoir7 aredrawn outward thronghthe upper end of said line (l.

lt will be seen that while during` the use otl the oven the gaseousproducts of combustiml are not forced to pass into thecl1a1|1be1'l,"ai1d that while heating' said oven said gaseous productshave parted with a portion oi' their heat,

upon reaching' the bottom ot' said chamber said gases will natu allyexpand into and cir culate through the same, while their temperaturewill still be far above the boiling-point, and sufficient for all of therequirements oi' the reservoir, and to insure aV good draft in theexit-flue. In addition to the heat of the current of gases, the rearoven-plate d will radiate rearward aconsiderablev quantity of heat,which, while aftordilig material assistance to the reservoir7 will notlessen the etiicielley of the oven, for the reason that at such pointsaid oven always possesses a surplus of heat, which can be sparedwithout injury.

Having thus fully set forth the nature and merits ofmy invention, whatIclaim as new is In a cooking-stove, a chamber for receiving,r andcontaining a water-reservoir, situated in rear of the vertical tlues andbelow the top plate, communicating at its lower side with the descendingfines, by means of dampered apertures, and, having; its front centralportion extendin g forward to the back oven-plate, substantially as andfor the purpose specied.

In testimony that I claim the foregoing, I have hereunto set my hand andseal this 14th day of January, 1874.
